Pentair Pressure Gauge for System 3 — 0-60 psi, 1/4" MPT Back-Mount OEM Replacement

The Pentair 24850-0105 is a back-mount pressure gauge assembly engineered to monitor System 3 pool and spa pressures from 0 to 60 psi via a 1/4" MPT connection.

Accurate pressure monitoring is essential for maintaining pool and spa equipment performance. This Pentair OEM gauge assembly is built to integrate with Pentair System 3 controllers and plumbing, offering a compact back-mount design and a standard 1/4" male pipe thread for straightforward installation. The 0–60 psi range covers typical filtration and pump pressure requirements so you can quickly see if a system is operating within expected parameters.

How will this gauge assembly fit into my existing Pentair System 3 equipment?

The 24850-0105 is designed specifically for Pentair System 3 compatibility, matching common ports and mounting orientations used on System 3 manifolds and panels. Its 1/4" MPT thread and back mount layout make alignment simple when replacing a failed gauge or upgrading instrumentation.

• Direct replacement for Pentair System 3 installs
• 1/4" male pipe thread for standard plumbing fittings
• Back-mount configuration for panel or manifold mounting
• Compact footprint fits tight control spaces

What pressure range and accuracy can I expect from the 24850-0105?

This gauge displays system pressure across a 0–60 psi scale—suitable for most pool pumps and filtration systems. While it provides quick visual readings for routine checks, it is intended for operational monitoring rather than laboratory-grade precision.

• 0–60 psi readable range for typical pool/spa systems
• Clear dial markings for fast visual checks
• Robust construction for poolside environments

How easy is installation and maintenance for this Pentair pressure gauge?

Installation is straightforward: thread the 1/4" MPT into the corresponding port and secure the back-mount to the panel or manifold. Maintenance generally involves occasional visual inspection and replacement if the dial becomes fogged or the pointer sticks; the assembly is intended as a field-replaceable component.

• No special tools required beyond wrenches and plumbing tape
• Back-mount design reduces exposed plumbing and simplifies wiring routing
• Replaceable unit—swap in a new assembly without complex calibration

What materials and durability features support outdoor pool environments?

Pentair designs its replacement components for the harsh conditions common around pools and spas, focusing on corrosion resistance and longevity. The gauge housing and fittings are selected to withstand humid, chlorinated, and chemically treated atmospheres typical of pool equipment rooms.

• Sealed housing to resist moisture ingress
• Durable dial face for UV and chemical exposure
• Metal fittings for secure, leak-resistant connections

Who this is for: The Pentair 24850-0105 pressure gauge assembly is ideal for pool service professionals, maintenance managers, and homeowners who use Pentair System 3 equipment and need a reliable, field-replaceable instrument to monitor pump and filter pressure. Choose this assembly when you want a direct-fit, back-mount gauge with a 0–60 psi scale and a common 1/4" MPT plumbing connection for quick, dependable integration into existing Pentair systems.
